1b66 Summary



The structure was published by Ploom, T., Thony, B., Yim, J., et al., Richardson, J., Huber, R., and Auerbach, G., in 1999 in a paper entitled "Crystallographic and kinetic investigations on the mechanism of 6-pyruvoyl tetrahydropterin synthase." (abstract).

This crystal structure was determined using X-ray diffraction at a resolution of 1.9 Å and deposited in 1999.

The experimental data on which the structure is based was not deposited.
